BOBBJN-HOLDER.

SPECIFICATION forming part Of Letters. PatentNo. 696,082, dated March25, 19 02 Application filed September 17, 1900. Serial No. 30,242. (Nomodel.)

To all whom it may concern:

Be it known that I, ORRIN M. ROLFE, a citizen of the UnitedStates,residing at Lowell, in the county of Middlesex and Commonwealthof Massachusetts,l1ave invented a certain new and useful Improvement inBobbin-Holders, of which the following is a specification.

My invention relates to bobbin-holders; and it consists of the devicesand combinations hereinafter described and claimed.

Bobbin-holders used in spoolers commonly comprise a trough in which abobbin is laid and from which it is prevented from jumping by a pair ofpivoted guard-wires arranged on opposite sides of the bobbin and havinga limited swinging movement, the guardwire at one side being heldagainst the cop on the bobbin by the tension of the yarn which is drawnfrom the top of said cop and passes down under the lower straightportion or tension-bar of said guard-wire and is then drawn upward tothe spool to which the yarn is to 'be transferred. The tension-bar orlonger lower portion of the guardwire is usually straight and parallelwith the axis of the bobbin contained in the holder. Usually only one ofthe guard-wires has any appreciable effect on the tension of the yarn,the other guard-wire merely assisting to retain the bobbin in theholder, but the holder having as many lateral openings as there areguardwires, the opening adjacent to the tensioncausing guard-Wireserving as a yarn-delivery opening. The body of the bobbin-holder issometimes made with a single opening and is provided with a singleguard-wire; but heretofore the bobbin has always been pushed endwiseinto the holder, because said guardwire is prevented from swingingoutside of the body of the holder and reaches so near the bottom of thetrough that the bobbin cannot be passed under i The object of thisinvention is to enable the bobbin to be placed laterallyin theholderthrough the side of the holder instead of being pushed lengthwise intothe front of the holder, thus effecting a great saving of time; todispense with one of the guardwires and to enable the bobbin to beinserted without first pushing the guard-wire aside; to steady thebobbin in the holder by so shaping the tension-bar that only its endwill bear upon the cop, and generally to sim plify, cheapen, and improvethe construction of said holders and to increase their durability.

In the accompanying drawings, Figure 1 is a right-side elevation of abobbin-holder containing a bobbin and cop and provided with myimprovement, the holder-supporting rod being in vertical cross-section;Fig. 2, a front elevation of the same; Fig. 3, a plan of the guard-wire,showing the curvature of its ten sion-bar.

The horizontal supporting-rod A and the clamp B and clamp-screw b, bywhich the holder is secured to the rod A, are of any usual construction.The clamp B is provided with an ear I), and the bodyO of thebobbinholder is also provided with an ear 0, said ears being adj ustablysecured to each other by a pivot-bolt D and nut cl, which being loosenedallows the holder to be set at the desired angle in a well-known manner.

The body 0 of the bobbin-holder consists of a trough 0, within which thebobbin E rests in the usual manner, a back ciwhich extends upward fromthe rear of said trough, and an arm 0 projecting forward from said backpar= allel with the bottom of said trough.

It will be seen that the body C is approxi-' mately a hollow cylinderhaving two lateral longitudinal openings and 0 between the arm 0 and thesides of the trough 0', one, o, of these openings being for the usualpurpose of a yarn-delivery slot, and this slot is closed against theescape of the bobbin E by a guardwire F of the usual form, except ashereinafter stated, which is pivoted in ears 0", cast or otherwisesecured on the under side of the arm 0 The outward-swinging movement ofthe guard-wire is limited in the usual manner, said wire strikingagainst the inner face of the wall of the body 0 back of the opening 0The slot 0 is arranged on the opposite side of the bobbinholder from theslot 0 the lower side of said slot 0 being arranged to be above the axisof a full bobbin to prevent said bobbin from rolling out of said opening0 said slot running lengthwise of the bobbin-holder and being ofsufficient width to allow a full bobbin to be dropped sidewise into thetrough. The tension-bar f or lower longer side of the guard-wire isconcaved on the face next to the bobbin, so as to bear only at its endsupon the cop e, and thus to insure the steadiness of the bobbin in theholder to a much greater degree than when the tension-bar is perfectlystraight, as the portion of the cop between the tapering ends c e ofsaid cop is not always perfectly straight, although intended to be so,the diameter of the cop sometimes varying between these points.

The arm a is most likely to be broken, as the spools when filled weighabout two pounds each and sometimes in dofling are carelessly dropped adistance of about eighteen inches upon said arms. The arm 0 is thereforepreferably made in a separate piece and is provided with a groove 0 toreceive the top of the back 0 and is attached to said back by a verticalscrew a driven through the top of said arm into said back. If the arm 0is broken by accident, it may be removed by loosening said screw 0 and anew arm substituted without throwing away the body of the holder.

I claim as my invention- 1. The combination of a bObblIl-hOldGlllitV-the part of the bobbin-holder ing an approximately hollow cylindricalbody, provided at one side with an unobstructed longitudinal opening toreceive a bobbin, the bottom of said opening being arranged to be abovethe axis of a full bobbin to be sustained in said holder, and providedon the opposite side with another longitudinal yarn-delivery opening,with a pivoted guard-wire to prevent the contained bobbin from passingthrough said last-named opening.

2. The combination with the body of a bobbin-holder, provided with ayarn -de1ivery opening, of a swinging guard provided with a tension-bar,co'ncaved on its inner side to hear at its ends only upon the endportions of the cylindrical surface of the cop of a bobbin arranged insaid holder to steady said bobbin in said holder.

In testimony whereof I have affixed my signature in presence of twowitnesses.
